为了适应电阻焊技术的发展,提高电阻焊机的自动化程度,针对电阻焊机的结构、应用场合,研究了一套基于光电编码器和PLC高速计数器的自动测厚装置。重点介绍了光电编码器的选型、结构、工作原理及其在该测厚装置中的实际应用。该装置能将所测数据自动反馈回焊机控制器,然后选择预先设定的与焊件厚度相对应的最佳焊接参数,以便焊机自动分次焊接工件。结果表明,该测厚装置能达到选择焊接参数的精度要求,能很好地满足实际生产的要求。
In order to adapt the development of the resistance welding technology and improve the automation of the resistance welding machine,an automatic thickness measurement device with the photoelectric coder and the PLC high-speed counter was studied based on the structure and application situation of the resistance welding machine.The type,construction,working principle of the photoelectric coder were especially introduced.And actual application in this thickness measuring device was expounded.This device can feed the measured data back to the controller of the welding machine automatically,then the best welding parameters correspond with the thickness of the weldment were chosed in advance in order that the welding machine can weld the work piece automatically in sequence.The experimental results indicate that this thickness measurement device can achieve the precision demand of choosing the welding parameters and can satisfy the actual production well.
